Decoding the PLU Code System
Those small stickers on your produce are not random labels; they are Price Look-Up (PLU) codes established by the International Federation for Produce Standards (IFPS). These codes provide grocery stores with a standardized way to identify, price, and manage inventory for bulk items like fruits and vegetables. While designed for retail, the codes also provide valuable information to consumers, particularly about how the produce was grown. The number of digits in the code and the starting digit are key to unlocking its meaning.
The Meaning Behind the Numbers
- Four-Digit Codes: A four-digit PLU code, like 3279, signifies that the fruit is conventionally grown. This means it was cultivated using standard farming practices, which may involve synthetic fertilizers and pesticides. These codes are typically in the 3000 and 4000 series.
- Five-Digit Codes Starting with '9': A five-digit code that begins with the number '9' indicates that the produce is organically grown. For example, an organic golden kiwi would have the code 93279.
- Five-Digit Codes Starting with '8': Originally, five-digit codes beginning with '8' were intended for genetically modified (GMO) produce. However, due to low consumer demand for labeling, this prefix is rarely used in retail. Some companies choose to label GMO items as conventional instead, making this prefix an unreliable indicator. As the 3000 and 4000 series become exhausted, the '8' and '9' series may be used for other purposes, adding a layer of complexity.
Unpacking PLU Code 3279: Golden Kiwifruit
So, what does 3279 mean on fruit specifically? This PLU code is assigned to a conventionally grown golden kiwifruit. Unlike the more common fuzzy green kiwi, the golden variety has a smooth, bronze-colored skin and a sweeter, more tropical flavor profile. The '3' in the 3000 series simply categorizes it within the conventional produce range, with the remaining digits specifying the item's variety and other details.
Golden kiwis are native to central China but are cultivated globally in regions like the Mediterranean and New Zealand. The sticker with the 3279 code helps the cashier quickly identify it at checkout, distinguishing it from other varieties and sizes of kiwi that might have different prices.
Making Informed Choices with PLU Codes
For consumers, understanding PLU codes empowers you to choose products that align with your purchasing priorities. If you prefer to avoid produce grown with conventional pesticides, knowing to look for a five-digit code beginning with '9' can guide your selection. For those focused on specific varieties, such as a golden kiwi, the four-digit code helps ensure you're getting the right fruit.
PLU Code Comparison Table
| PLU Code | Number of Digits | Cultivation Method | Example Product | Potential Price Point | 
|---|---|---|---|---|
| 3279 | 4 | Conventional | Golden Kiwifruit | Lower to Moderate | 
| 93279 | 5 | Organic | Golden Kiwifruit | Higher | 
| 4011 | 4 | Conventional | Bananas | Lower | 
| 94011 | 5 | Organic | Bananas | Higher | 
| 4128 | 4 | Conventional | Pink Lady Apple | Moderate | 
| 94128 | 5 | Organic | Pink Lady Apple | Higher | 
This table illustrates how the presence or absence of the '9' prefix, and therefore the cultivation method, affects the PLU code and can correlate to the product's price.
Navigating Grocery Store Produce
Beyond PLU codes, there are other ways to identify produce, though the stickers provide the most reliable insight at checkout. Many stores also use signs to indicate growing methods, but the voluntary PLU system offers a quick, standardized reference point. It is important to note that the PLU system is not a legal requirement for labeling and is administered by a voluntary organization, not a government body.
- For the Health-Conscious Shopper: If you prioritize limiting pesticide exposure, focusing on items with five-digit PLU codes beginning with '9' is a reliable strategy. For produce with thick, inedible skins like bananas and avocados, conventionally grown options are generally less of a concern.
- For the Budget-Conscious Shopper: Understanding that the higher price point for organic produce is directly tied to the '9' prefix can help you weigh your options. You can save money on items where the growing method may be less of a priority for you.
- For the Environmentally-Conscious Shopper: Choosing organic options (indicated by the '9' prefix) supports farming methods that, by definition, avoid synthetic fertilizers and pesticides, which promotes soil health and biodiversity.

Conclusion
The next time you see a small sticker on your fruit, you'll know it's not just a random sequence of numbers. The code 3279 means that the fruit is a conventionally grown golden kiwifruit, while other codes reveal different growing methods and varieties. Decoding these PLU codes is a simple yet powerful skill that allows you to make confident and informed purchasing decisions at the grocery store, whether you prioritize health, budget, or environmental impact.
